Spirit Airline Baggage Policy
Spirit Airlines doesn’t include bags in its base allowance (Bare Fare). Additionally, baggage prices rise the closer you get from take-off. Your best option is to purchase your allowance at the time of your first booking.

Another thing to consider: Spirit’s baggage policy stipulates that the maximum bag weight is 40 pounds (18 kilograms). This is 10 lb (5 kg) less than the average and you can be sure you will pay more for it.

Standard Carryon Bag:
The fees vary depending on where you are going and when you buy your bags. Spirit recommends that passengers use its baggage calculator. We found the following consistent fees after doing a few searches. However, please make sure you check the route for which you are traveling.
